You can go past 0, there is a built in safety which has been reported at about 20 miles. Some have even reported going as far as 40 miles past 0. Your best bet is to watch the gallons in Trip 1, don't go past 13.00 gallons and you should be fine. In your case, 13 - 7.53 = 5.47 gallons; 5.47 gallons * 46.4 mpg = 253.8 miles. That puts you over 600!!!

I have not run out of gas so I can't tell you exactly what to expect, but if you do run out of gas make sure you use the little funnel in the trunk to fill it up. (that's what they recommend anyway)

Wow, what a great find! I always knew work was at a lower elevation than home but I had no idea it was almost a 400 foot difference! I normally hit 80-85 mpg about the 10 mile mark, and then drop down to 70-75 over the last couple miles, that is perfectly explained here as well! I have gotten my home mileage up to 45-50 depending on traffic and whatnot, I'm amazed I am getting that with the hills I have to climb! Drive to work: Drive home: Just for fun, here is the hill by my house I used to go up and over everyday before I decided to drive around it, 150 feet up on one side and 175 feet up on the other. I did make this trip to get a haircut up and over the hill and back during my 686 mile tank, short 4 mile round trip with a cold car I burned 0.25 gallons, which is way more than I burn driving 12.3 miles to work!

Thanks C-MaxSea! You are correct though, it is not easy. That tank was 3 weeks worth of driving for me, (Aug. 24th - Sept 13th) and during that time there were 5 trips that hurt my average. - I got a haircut that is only a 4 mile round trip from my house but it is up and over a massive hill, I averaged 22 mpg for the trip which means I burned almost 0.25 gallons, way more than I burn on my daily trip to work that is 12.3 miles long. - I drove to my friends house and my girlfriend insisted on the air conditioning. I still got 50 mpg for the trip but it is a 75 mile round trip, so that is almost a tenth of my whole tank well at well below my average mpg. - I drove home twice with the air conditioning on before I was thinking 700 mile tank, both days I averaged about 48 mpg for the round trip to and from work, another 50 miles on the tank well below my average mpg. Even with the above, I still had a shot. You need to average 53.83 mpg over 13 gallons to hit 700, I was at 54.0 mpg on Thursday after getting to work, but my hopes were dashed on my way home from work. - Thursday night I drove home in a crazy storm, got hailed on, was stuck in ridiculous traffic, and drove through countless puddles, ended up at 36 mpg for the trip which dropped me from 54.0 mpg to 53.5 mpg after already driving 650 miles! An average day driving to and from work for me is between 54-56 mpg, I set a couple of personal bests the past couple weeks including a 58.6 mpg day. In the end it didn't matter, those 5 trips over 3 weeks killed my chances at 700 miles. As Jus is always saying, consistency is the hardest part...

Well, don't I feel like the wuss! I cashed in my chips and filled up this morning at 686.9 miles, 53.5 mpg and 12.83 gallons burned. After driving home in the storm yesterday and nosediving from 54.0 to 53.5 mpg I didn't safe pushing it past 13 gallons when I've heard others running out of gas under that number. Oh well, my miles to E said 723 miles right after I filled up so I hope to get to 700 miles on this next tank! I'll be back in a month or so after I actually drive all those miles. Edit: For those that are interested I only pumped in 12.6 gallons this morning, so my smart gauge was a little high and I probably had plenty of gas to hit 700...

I'm in the same boat ptjones, I had a shot but got stuck in a storm driving home today and my normal 45-50 mpg trip home ended up at 36.6 mpg. That burned way more gas than I could afford so I will likely end up 10 miles short too. I've burned about 12.8 gallons and have 17 miles to go... Oh well, there is always the next tank!

Well here is what will be my best entry for the 500+ max mpg club, 54.0 mpg over 668.8 miles (12.38 gallons). No way I top this tomorrow because I drove home through a huge storm, got hailed on, sat in traffic, drove through puddles galore, and averaged 36 mpg for my trip home... The whole time I was sweating bullets, just thankful I made it home! I'm not making my 700 miles this tank, I ran in the house because of the rain but I'm about 683 miles and I've burned 12.8 gallons for the tank, so I'm not making 17 miles on 0.2 gallons. I'm just going to drive to the gas station down the street from me tomorrow morning and fill up, I'll post that picture tomorrow night or this weekend. Oh well...

I set two personal records today, best trip to work and best round trip to work! Trip to work was 77.1 mpg (previous best was 76.1 mpg) and for the round trip I hit 58.6 mpg! (yesterday was my previous best round trip at 56.7 mpg) It helped that I hit traffic on the way home, the section of highway I normally drive at 55 mph I never topped 45, and combined with my personal best trip this morning I easily beat my previous best round trip. I'm also got up to 53.8 mpg for the tank when I got to work (641.6 miles and 11.91 gallons), I'm holding off on posting that picture because I want to wait and see if I can do better tomorrow or Friday. I really think I have a chance at a 700 mile tank, if I have 13 gallons to burn then I need to hit 53.833 mpg. I'm right there and if I continue to get record or near record trips to work I will pass 700 just as I get to work on Friday the 13th! Ha!

What is the absolute MAX gallons that I can burn before running out of gas? So close to 700...

Understood on both points... Have you thought about switching so that she drives there and you drive home?

Eco-cruise is part of your problem, if you don't want to pulse & glide all the way home why don't you try tapping down on the speed setting 1 mph when in eco-cruise to induce EV mode on some of the hills? Even with gradual downhills EV can hold on a pretty good distance. When I was coming home from my vacation I held 65 mph for 12 miles on Rt. 80 East at the Pennsylvania / New Jersey border. If that doesn't work are you willing to slow down a little? A 10 mph difference is huge on the gas mileage at higher speeds.

I got 56.7 mpg round trip today to work and home, that's a personal record! When I got to work trip 1 said 53.7 mpg and when I got home it was down to 53.5. This makes me really angry about the couple of days I drove home with the AC on and got 48 mpg round trips, when I went up to my friends house and my girlfriend insisted on using the air, and the time I went up and over this giant hill near my house when I went to get my haircut instead of driving around it, short 2 mile trips that ended up in the low 20 mpg's both ways... On top of that it's supposed to be in the mid-90's here tomorrow, ugh... I want the 700 miles to be in my normal driving routes, not going to go out of my way to get a higher mpg, but I won't lie, I'm tempted... I know a 5 mile route with a gas station at the bottom of the hill that I can easily hit 100 mpg for the trip (assuming the lights work out for me) but coming home is a bear so I'd have to do that for my last 5 miles. I couldn't imagine 800, my highest round trip ever was today at 56.7 mpg, I'd have to up that a full 5 mpg and AVERAGE that over 800 miles... The only way I could see that happening is if I had a tow truck pick me up from work everyday for a month or so... Lol!

I'm seeing about a 2 mpg boost from before the update, but it could also just be my car breaking in so who really knows. Before my update my best tank was 647 miles @ 51.4 mpg. Right now I'm at 603 miles and 53.5 mpg, and I still have about 1.75 gallons left.

People have said they can go about 20 miles past 0, but I have not done it myself. I am at 603 miles for my current tank and I still have about 1.75 gallons left. That puts me really, really close to 700 miles. I'm think I'm going to get a can and a gallon of gas to give it a run. When I was at my parents house before I looked at trip 1 and it said 588.4 miles, 10.99 gallons, and 53.5 mpg. I took a pic, but I'm going to hold off posting it to see if I can get a higher average. I'll post the best one after I fill up so I'm not updating my 500+ mpg daily.
